0016873: Kernel Crash

0015471: SELinux is preventing /usr/bin/evince-thumbnailer from using the nnp_transition, nosuid_transition access on a process.
Description of problem:<br />
after updating using yum4 update on 17/11/2018<br />
SELinux is preventing /usr/bin/evince-thumbnailer from using the nnp_transition, nosuid_transition access on a process.<br />
<br />
***** Plugin catchall (100. confidence) suggests **************************<br />
<br />
If you believe that evince-thumbnailer should be allowed nnp_transition nosuid_transition access on processes labeled thumb_t by default.<br />
Then you should report this as a bug.<br />
You can generate a local policy module to allow this access.<br />
Do<br />
allow this access for now by executing:<br />
# ausearch -c 'evince-thumbnai' --raw | audit2allow -M my-evincethumbnai<br />
# semodule -i my-evincethumbnai.pp<br />

0016572: Unable to "login" to Centos8 when using VNC.
I'm using a Windows 10 machine with VirtualBox 6.<br />
I have successfully installed Centos 8 and TigerVNC.<br />
I have successfully connecter to the Centos 8 machine via TigerVNC (I am using RealVNC vncViewer).<br />
<br />
Unfortunately, when trying to login the "next" button is constantly being "clicked".<br />
This prevents me from typing in the password and instead I keep receiving an "Authentication error" message.<br />
<br />
I suspect the Vncviewer is sending an "input" causing the "next" button to be "clicked".

0016355: Local printer script not working with the latest Samba update 4.8.3-6.el7_6
Hello,<br />
<br />
With the recent Samba update I start seeing a lot of pending printer jobs in the queue, and I've found out that if I undo the last Samba update all printing jobs are working again.<br />
<br />
I've a Samba printer share that executes the 'enscript' command to format a text plain listing and send the job to another Samba printer share to convert it to PDF (with 'ps2pdf').<br />
<br />
This printer stop working right after updating the following packages:<br />

0016876: 404 "Not Found" error while trying to download archive with Linux kernel sources at https://git.centos.org/rpms/kernel/releases
When I try to download an archive with Linux kernel sources at <a href="https://git.centos.org/rpms/kernel/releases">https://git.centos.org/rpms/kernel/releases</a> , i.e. imports/c8s/kernel-4.18.0-151.el8 , I get a 404 "Not Found" error. Your website generates the links like <a href="https://git.centos.org/rpms/kernel/archive/imports/c8s/kernel-4.18.0-151.el8/kernel-imports/c8s/kernel-4.18.0-151.el8.tar.gz">https://git.centos.org/rpms/kernel/archive/imports/c8s/kernel-4.18.0-151.el8/kernel-imports/c8s/kernel-4.18.0-151.el8.tar.gz</a> and <a href="https://git.centos.org/rpms/kernel/archive/imports/c8s/kernel-4.18.0-151.el8/kernel-imports/c8s/kernel-4.18.0-151.el8.zip">https://git.centos.org/rpms/kernel/archive/imports/c8s/kernel-4.18.0-151.el8/kernel-imports/c8s/kernel-4.18.0-151.el8.zip</a> , but either they are incorrect or the archives are missing

0016875: "The remote end hung up unexpectedly, early EOF" while doing a "git clone --branch c8s https://git.centos.org/rpms/kernel.git"
It seems impossible to git clone a c8s branch of CentOS 8 Linux Kernel without getting a "The remote end hung up unexpectedly, early EOF" error which interrupts the operation. Tried all the available client-side workarounds like "git config --global http.postBuffer 1073741824" and "export GIT_HTTP_MAX_REQUEST_BUFFER=1024M" but nothing works. However, cloning the other repositories - even the huge ones - is working OK, so I'm confident there is a problem with your repository.

0016877: centos-release provided /etc/os-release file missing info needed to resolve modular platform ID
Neal Gompa recently built livecd-tools for EPEL8/EPEL8PLAYGROUND which provides livecd-creator. I'm trying to use livecd-creator (which I'm very familiar with from EL7 and Fedora) to build CentOS 8 remixes but it is unable to resolve all of the modular dependencies and fails. See attached file for error listing.<br />
<br />
According to Neal, the /etc/os-release file provided by the centos-release package is missing some file that is needed to auto-discover the modular release ID... which he says is CentOS specific.<br />
<br />
Hopefully after filing this bug report I can get Neal to add some additional details as to what the problem is and how it can be fixed. I believe it is a non-code, one liner... and if I knew what it was, I'd submit a patch myself.

After update to CentOS 7.7 with kernel 3.10.0-1062.1.1.el7.x86_64 the built in network card shows NO-CARRIER. When I boot to previous kernel - 3.10.0-957.27.2.el7.x86_64 the network card works fine. I'm not 100% sure about the network card model. lspci shows Realtek RTL8111/8168/8411.

0016715: Missing SRPMs in CentOS 8-stream
Hello,<br />
<br />
As mentioned in [0] it looks like CentOS 8-stream is missing[1] SRPM packages, which makes commands like `dnf builddep <package>` fail. Is there any plan to populate source repositories for 8-stream as well?<br />
<br />
Thanks!<br />

0016856: RRDTool creates folders/files with arbitrary permissions
Description of problem:<br />
<br />
When you use rrdtool-1.7.0-16.el8 in tools that use it in a multithreaded way, e.g. Collectd or OpenNMS, it will create folders/files with arbitrary permissions.<br />
This is a known issue described and solved in RRDTools issue tracker[1]. We ran into this issue in OpenNMS[2] as well. We were able to see this error in rrdtool-1.7.0-16.el8 and after upgrading to 1.7.2 the problem was solved.<br />
<br />
I've looked up the AppStream 8 source repository[3] for RRDTool and it seems this patch is not backported to RRDTool 1.7.0. As described in RRDTool it would be required to upgrade RRDTool at least to 1.7.1 or backport the patch to RRDTool 1.7.0.<br />
<br />
This issue is reported also in Red Hat Bugzilla[4].<br />

0016883: Install will not support release of disk space on USB drives
I have successfully install Centos 7 on a USB attached drive on this system a number of times. When attempting the same with Centos 8 (1905), I go through the reclaim space options, select either individual partition remove or remove all. But this always fails to free up space. I am therefore unable to continue with the process.
